# Event - Async IO similar to libevent
Event is a lightweight IO library for Rust with a focus on adding as little overhead as possible over the OS abstractions.

[![Build Status](https://api.travis-ci.org/tickbh/td_revent.svg?branch=master)](https://travis-ci.org/tickbh/td_revent)

Getting started guide Currently a work in progress:

##Usage

To use td_revent, first add this to your Cargo.toml:
```rust
[dependencies]
td_revent = "0.3.0"
```
Then, add this to your crate root:

```rust
extern crate td_revent;
```

Add empty event just do
```rust
extern crate td_revent;
use td_revent::EventLoop;

fn main() {
    let mut event_loop = EventLoop::new().unwrap();
    event_loop.run();
}
```
Add simple timer event just do

```rust
extern crate td_revent;
use td_revent::{EventLoop, EventEntry, EventFlags};
use std::ptr;

fn time_callback(ev : &mut EventLoop, fd : u64, _ : EventFlags, data : *mut ()) -> i32 {
    println!("fd is {:?}", fd);
    //return 0 status ok other will delete the timer
    0
}

pub fn main() {
    let mut event_loop : EventLoop = EventLoop::new().unwrap();
    event_loop.add_timer(EventEntry::new_timer(100, false, Some(time_callback), None));
    event_loop.add_timer(EventEntry::new_timer(200, true, Some(time_callback), None));
    event_loop.run().unwrap();
}
```
##Features

Event loop backed by epoll, windows by select.
Non-blocking TCP sockets
High performance timer system

##Platforms
Currently, td_revent only supports Linux and Windows. The goal is to support all platforms that support Rust and the readiness IO model.
